Metagenomic and transkription analyzes of partial nitration-anammox (PNA) processes in wastewater treatment

Partial nitritation-anammox (PNA) for nitrogen removal from municipal wastewater enables energy efficient nitrogen removal with low climate impact. Today, PNA is used for treatment of the warm and concentrated sidestream from anaerobic digestion, but not for the colder and more diluted mainstream of wastewater holding most of the nitrogen at wastewater treatment plants. To reach a stable process solution for the mainstream, more knowledge about the microbial interactions is necessary. Here, we investigate the diversity and function of the bacteria carrying out the PNA process by metagenomics and metatranscriptomics in various PNA reactors for sidestream and mainstream treatment.
